Eltrombopag induces Akt in human platelets and immature megakaryocytes. (A) Platelets from a healthy donor or (B) multiple myeloma-derived peripheral blood mobilized-CD34+ cells (MM#1 and MM#2) cultured for 8 days were stimulated with 100 ng/ml rhTPO or 10 μM eltrombopag for the indicated times, and immunoblotting was performed to detect the activation of STAT5 and Akt signaling pathways. Note that p-Akt bands appeared below non-specific bands in human platelets (A) and above non-specific bands in immature megakaryocytes (B). Migration of molecular weight markers is indicated to the right of each blot.
